Reaction Steps

To a suspension of NaH (7.5 mg, 0.19 mmol) in DMF (1.25 mL) at 0° C. under argon was added 5-[2-fluoro-4-(1-hydroxy-1-methylethyl)phenyl]-2-{[6-(hydroxymethyl)pyridin-2-yl]amino}thiophene-3-carboxamide (Example 43) (50 mg, 0.13 mmol) and the mixture was allowed to stir for 10 minutes. 1-Bromo-2-methoxyethane (26 mg, 0.187 mmol) was then added and the reaction was allowed to warm to room temperature overnight. The reaction was then quenched by the addition of water, extracted with ethyl acetate and concentrated in vacuo. The crude residue was reverse phase HPLC (acteonitrile/water with formic acid as a modifier) to afford the title compound.
